Final answer:
In fog or rain, it is advisable to use low beams to improve visibility while minimizing glare for yourself and other drivers. High beams can reflect off precipitation and worsen visibility, and flashers should only be used when traffic conditions require it.
Step-by-step explanation:
When driving in fog or rain, it is advisable to drive with low beams. High beams can reflect off the fog or rain droplets, causing a glare that can reduce visibility even further. Flashers, or hazard lights, should only be used if you are stopped or moving significantly slower than the flow of traffic, as using them while driving can confuse or mislead other drivers.
Low beams provide adequate lighting while minimizing glare for other drivers. Having your headlights on, whether it is day or night, increases your visibility to other drivers, which is essential for safe driving in poor weather conditions. Always remember, safety should be your priority, and adjusting to weather conditions by using appropriate lighting helps ensure not only your safety but that of others on the road as well.
